I read in La Voz today (could not find the article online) that there are pilgrims arriving to the albergue in Finisterre. They report of walking through several kilometers of burnt forest. One Spanish couple (from Madrid I think it was) said that they actually thought it would be worse, since they had seen the fires on TV before leaving home. They said something like "It is clear that the fires has burnt quite a lot, but the Camino experience is still the same".
... so I think the conclusion for now on the route out to Finisterre is that it can be walked, there are rooms in the albergues (they had pictures from the albergue in Finisterre and the article did not mention any problems, so I assume so) but that there are some stretches were you need to walk in burnt land.
I will try to keep you all updated when I hear something new...
By the way, the weather has changed again... now blue skies and the temperature is supposed to get to the mid 20s.
Un saludo,
